Casement lock for Ducana Window

I am looking for replacement lock. On the side of the lever are the following:-
U.S. PAT. 5.620.213 and CDN. PAT. 2.142.071

Can you please help me?

Thank you for posting! I do not think we have an exact match for this latch, but please see our 38-090 SilverLine Casement Locking Handle. Do you think you can use this as a replacement? Let me know.

The windows in our home do not have a name on them. The part I looking for is the window lock. There is a number on the locking mechanism. It appears to be for a Canadian Patent - #CA 2142071.

Thank you for posting, and for the great pictures! I have placed you into an existing thread concerning this part. Now, as Dave said above, we do not have this exact hardware, but please take a look at our 38-090 SilverLine casement Locking Handle. Could you perhaps use this as a substitute?

Has anyone tried the Silverline 38-090 for a replacement for the above casement lock? I am looking for replacements as well.
